In the offered review ordering received and published by domestic and foreign researchers of the experimental results showing the phenomenon of a photoluminescence in glasses and optical fiber, activated by bismuth is executed, and from uniform positions representations about the process responsible for a photoluminescence in case of use for excitation of this environment of various laser sources are considered. At interpretation of process of a photoluminescence the known model considering mirror symmetry of features of frequency spectra of a photoluminescence (in this case the maximum values is used: humps or peaks of spectra of a photoluminescence) and the spectra characterising optical losses (absorption) of glass, activated by (atomic) bismuth. For the analysis values of lines of the bismuth, published in reference media are used. This model is added by earlier published specification of the author, according to which to a point of mirror symmetry of such spectra there corresponds frequency of radiation of the source raising a photoluminescence - mean arithmetical of the frequencies of peaks of spectra of a photoluminescence and frequencies of lines atomic bismuth.
